To the 75 xo keyf, which is driven horizontally through forward end of this lever Z9 is jointedaspringthe bolt V and which is provided with a head pressed arm y, which points upward and is f' for keeping it in position. The firing-pin vadapted to engage 'with its hooked end into l.is furthermore provided with a rest d, into a corresponding hook of the 'scar A, pivoted which .may engage the spring-actuated s-ear in the coupling-piece K of the bolt. lVhen 8o z5 A, which ispivoted in the coupling-piece Kf the trigger Z is pulled back, the hook of the AS seen from the diagram, Fig. 9, the locltl'f a-rm y cannot engage in-tc the correspon-ding ing grooves or recesses q are not at right anliook of the seal-A.

In the annexed drawings I' have also shown by Way of example a safety for preventing the accidental release ofthe firing-pin. This safety consists of a shaft o, passing transversely through the receiver and provided with a handle or thumb-piece O for giving it \Vhen the handle O is turned down, the shaft o rests against the rear slanting surface k of the scar A, and thus prevents this latter from being pulled down out of engagement with the cocked firing-pin. In this position the shaft 0 also rests in a depression or recess o' of the boltV, whereby the bolt is also prevented froin being opened. When the handle O is turned up, a flat or recessed part of the shafto faces the sear A and the 2o breech-bolt, so that these parts are not Vprented from operating.

7hat I claim. is- 1. In firearms, the combination with aI rigid or stationary barrel of an automatic straight 2 5 or sin gie-motion breech-bolt, essentially consisting of the bolt proper Y and of the bolthead K provided with locking-lugs u' placed at "a certain pitch, bolt Y and head K en gaging with cach other by nleans of a screwthrcad, and bolt Y provided with lateral guideribs 9:, of a receiver provided with guidegrooves I .and locking grooves or recesses q of a pitch corresponding to that of the lockinglugs w, and of a spring S; substantially as and for the purpose described.

i. In firearms7 the combination with a rigid or stationary.' barrel of an 'automatic straight or single-motion breech-bolt, essentially consisting of the bolt proper Y, a coupling-piece K/ and of the bolt-head K. provided with lock* ing-lugs 11: placed at a certain pitch, bolt V and head K engaging with each other by nieans of a screw-thread, and bolt V providedv 'with lateral guide-ribs of a receiver pro vided with guide grooves Z and locking grooves or recesses q of a pitch corresponding to that of the locking-lugs w andlof aspring S; substantially as and for the purpose described.

3. In firearms, the combination with arigid or stationary barrel of an automatic straight or single-motion breech-bolt, essentially consistin g of the bolt proper V, a couplii'igpiece K with the sear A pivoted thereto and of the bolt-head K provided with locking-lugs fil* placed ata certain pitch, bolt V and head K engagingwith each other by means of a screwthread and bolt V provided with lateral guideribs of a receiver provided with guide grooves Z and locking grooves or recesses q of a pitch corresponding to that of the'locking-lugs zu, and of a spring S, substantially as and for the purpose described.

4. In firearms with a rigid or stationary barreland an automatic straight or single-n1o tionbreeeh-bolt of the kind herein described, a device for cooking the ring-pin consisting of a key f inserted into the breech-bolt and engaging intoa slit f in the firing-pin; substantially as an'd for the purpose described.

In testimony whereof I have aflixed iny signature in presence of two Witnesses.
